` "gsicificatii; afnemers Patent No. 12,652, dated April s, `1855.

"Be" known.` that Ll Enos `WooDRUrr5 "plof Elizabethtown`,`fin the county of Essex, State ofNefwJersyhaveinvented anew vand Im" proved Mode offOperating a Rotating Gate; andl dohereby declare that the following is afu'lltand exact description thereof, referencebeing had to the drawings and model makefpart thereof." f

"Eigurel-represents a gate to be of any de` sired `pattern;` `inlength `suiicient to shut across two carriage "jways, isaid gate being hung upona` roundiiron lbar the ends of which are heldoneyinjthe top `crosspiece of L the framework as atfB1 andthe bottom end i @is held by the@ sill orafblock Ifast in `theV ground, thebarsandjLthe. gate `revolve together, the'upperend of the bar A projects r `upward"intothe hollowccornice and has two ropes or `chains D "attached thereto said ropes Aorchainspassing over pulleys fastened on i the top ofthehollowuprights of the frame Jhavetheweights Esuspended ontheir ends, these weights are.wound..;up `by turningthe gate round backward- The vgate `is held i shutby `the-latchesfF'and` the catch G "a 7 similar catchbeinguponveach post holds the jgate when open. f'lhese catchesas shown at Fig. 2 are double having one side X higher i than the othertolstop the gate when closing y `andat the 'same time to allow the latch to pass `over reelyujwhenthe gatefis turned backward tof wind` `itl up. `The two` latches are caused to lift `simultaneously'by the cross ties I: Figs `l. An uprightrod O passes l through theJcatfchjGas at J Eig.' 2 `up to the under sideof the latch, the lowerend of this rodisattached tof` ailever K lying parallel with `the carriage" way which lever extends y to aflength to admit acarriage and horse to J fstand clear of thegate"when closed thewheel ofthe carriage restingupon the crank lever L7 this' crank lever `lying across the wheel on the posts At thefoot of each post H al crank lever S y As a preventative to the opening of the gate by the tread of an animal a second y has its end projecting over and resting Y `upon the lever K-thepressure upon K by L causes the upright rod o to lift thelatch E out of thecatch `Gr the weights 'causing `the gate to commence a\ro`tation,.which is stoppedand the gate held open by the catches is laid across the wheel track which lifts the latches when the wheel passes over it and allows the weights to close the gate.

crank' lever M is placed at such a distance from L that the two cannot be trodupon at the sametime but near enough to allow va "carriage wheel to press upon L before it is clpar ofiM. An iron rod N` is attached to a i wedge` orblock P which is fast to the arm Q and moves upon a pin-this block or wedge being under the projectingend of the crank lever L prevents it romfpressing upon the long lever K, the carriage wheel by coming irst upon M removes the block from under the end-of L and allowsit to press upon K `and lift the latches F and the gateto open.

What I claim as my invention and desire to secure `by Letters Patent isw r p 1. Applying weightsin manner speciiied or any similar manner to the operating the Orate. r i? 2.1Theapplication to such gates of-` the manner herein described of causing both latches to lift at the same time.`

`3. The applicationof latcheswit-h one side higherthan the other to a rotating gate. 4. The manner above described of preventing the treadof an animal from opening the `gate or any `mode analogous thereto."
